I obtained a PB1400 NewerTech EtherTech PB10 in a parts lot off eBay. When I tried it in my 1400, it was dead, and did not appear in Apple System Profiler. Upon closer inspection, it seems to be missing a component! Does anyone know what goes in the red box on the image?

Alright, I've been studying other ethernet cards, and this looks like a location for a quartz oscillator, probably somewhere between 20-25 mHz (kHz?). Does anyone know the exact frequency? Otherwise, i'll just have to order the entire range from Digikey
